YANEZ ARAUZ, Juan M et al. Osteosíntesis mininvasiva con placas bloqueadas en fracturas metafisarias distales de tibia: Comparación de resultados entre fracturas AO 43A y AO 43C. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2015, vol.80, n.3, pp.185-195. ISSN 1852-7434.

Introduction: Distal tibial fractures are a therapeutic challenge due to the limited coverage and specific vascularization. The aims of this study are to analyze the clinical outcome and functional results in patients with tibial fracture treated with MIPO technique with locked plates, and to compare AO 43A and AO 43C1-C2 fracture results, and conventional open treatment with MIPO technique. Methods: Between 2004 and 2012, 32 distal tibial fractures treated with MIPO technique were evaluated. The 59.4% were AO 43A fractures and 40.6% were AO 43C. Mean follow-up: 39.6 months using AOFAS Score and X-rays. Complications were recorded. Results in AO A and AO C groups were compared. Results: Mean postoperative AOFAS score was 95.89 and 92.15 in AO A fracture and AO C1-2 fractures respectively. The mean time of weight bearing was 8.7 weeks. The mean time to return to activities was 9.3 months. Complications were detected in the 18.75% and removal of the hardware was necessary in 14 cases. Conclusions: Minimally invasive plate osteosynthesis is a good choice for tibial distal fractures, clinical and functional outcomes are good, and there are fewer complications in comparison to open surgery. AO 43A fractures have less complications than AO 43C with this technique.
